DRAFT SHIFTING AND HOLDBACK ATTACHMENT FOR GRAIN-HEADERS.

SPECIFICATION forming part of Letters Patent No. 673,917, dated May 14, 1901. Application filed June '7, 1900. serial No. 19,428. (No model.)

To all whom it may concern.-

Be it known that I, DELBERT F. MILLER, a citizen of the United States, residing at Antelope, in the county of Stark and State of North Dakota, have invented a new and useful Draft Shifting and Holdback Attachment for Grain-Headers, of which the following is a specification.

My invention is an improved draft shifting and holdback attachment for grain-headers, one object being to provide improved means whereby the team may be enabled to hold back when the heading-machine is being used in descending an incline.

Another object of my invention is to provide means whereby both teams may be turned at an angle with relation to the pushbar or tongue of the header, so as to cause the machine to be turned within ashort space.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view of a draft shifting and holdback attachment embodying my improvements, showing the same arranged in operative position on the rear side of the frame of a grain-header. Fig. 2 is a sectional view of the same on a plane indicated by the line a a of Fig. 1. Figs. 3, 4, and 5 are detail views. Fig. 6 is a side elevation.

The tilting-lever 1 of the header is provided near its front end with a transversely-disposed tubular bar 2, which is secured thereon by a yoke 3, the said yoke passing around bar 2 and through the vertical block 5, the block 5 being disposed at a suitable distance from the front end of the tilting-lever and secured thereto by a clip-bolt 6. The forward end of said yoke is attached to an upright post of the tilting-lever by means of one end of a clipbolt. Annular heads 8 are secured on the ends of the tubular cross-bar2, and to the said annular heads are bolted suitable braces 9 10. The braces 9 extend forward and downward and are bolted to the rear side of the header-frame A, and the braces 10 are disposed forward and upward and are bolted to upper parts of the header-frame or braces.

A pair of rings 11 are loosely disposed on the tubular cross-bar 2, one on each side of the tilting-lever, said rings 11 being adapted for the attachment of the holdback-straps or neck-yokes of the teams. The said cross-bar 2 is provided on its under side with a slot 12, which extends to the left of the tilting-lever. A bar 13 is disposed in the tubular cross-bar 2 and adapted to slide longitudinally therein and laterally and at right angles with relation to the push-bar or tongue. A ring 14 is loose on that portion of the tubular crossbar which extends to the left of the tilting-lever, and the said ring is secured on its under side to the bar 13 by a bolt or other suitable device, as at 15, the said bolt working in the slot 12.

On one side of the tilting lever is disposed alongitudinalshaft-rod16. Thesameisjournaled atits frontend in the block 5 and has its bearings near its rear end in the U shaped block 17, the said block 17 being secured on one side of the tilting-lever by means of bolts or other suitable devices, as at 18. A beveled pinion 19 is fast on the shaft-rod l6 immediately in advance of the U shaped block 17. and a similar pinion 20 is loose on said shaftrod immediatelyin rear of the said block. A spindle, which is here shown as formed by a bolt 21, projects from the outer side of the block 17, and on the said spindle is mounted a beveled gear-wheel 22, which engages the fast and loose pinions 19 20. The fast pinion 19 and beveled gear-wheel 22 serve to communicate power to the shaft rod 16. The loose pinion 20 may be omitted, if desired, its function being to relieve the spindle-bolt 21 of stress. A stop-slide 23 is supported in a suitable guidenotch 24, formed in the block 17, at the front end thereof, the said stop-slide being adapted, by engagement with the fast pinion 19 on the shaft-rod 16, to lock the latter against rotation. The said shaft-rod is providedat its front end with a pinion 25, which is fast thereon, the upper side of which extends through the slot 12 in the lower side of the tubular cross-bar 2 and engages a rack 26 on the lower side of the bar 13, which is longitudinally movable within thetubular crossbar 2. The gear 22 is provided with suitable means, as a crank 27, whereby it may be rotated in either direction in order to rotate the shaft-rod 16 in either direction, and thereby move the bar 13 longitudinally in the tubular cross-bar 2, and hence move the ring 14 laterally on said tubular cross-bar toward or from one side of the tilting-lever.

The operation of my invention is as follows: The inside horse of each team is hitched to the laterally-movable ring 14 by a suitable strap or jockey-stick extending from said ring to the bridle, and the holdback-straps or yokes of the teams are attached to the rings 11, as before stated. By operating the shaft 16 so as to cause said shaft and the bar 13 to move to the left in the tubular cross-bar 2 the said ring 14 is moved to the left, thereby turning the heads of the horses in that direction, and hence disposing them at an angle to the pushbar or tongue, and hence causing the header to be turned to the right. By thus providing means whereby the attaching device on the cross-bar may be adjusted laterally the horses may be disposed at such an angle to the pushbar or tongue as to enable the header to turn in a very'short space, as will be understood.

The cross-bar 2, with the rings 11 thereon, forms ready means for the attachment of the holdback-straps or neck-yokes of the teams, thus enabling the horses to hold back on the header when the same is being operated in descending an incline.

The stop-slide 23 may be moved into engagement with the pinion 19 to lock the latter against rotation, and thereby secure the sliding ring or attaching device at any desired position on the cross-bar 2.

Having thus described my invention, I claim- 1. A grain-heading machine having an adjustable header-frame, and a lever to tilt said header-frame, in com bination with a cross-bar attached to said tilting-lever, said bar serving for the attachment of the neck-yoke or holdback-straps of the teams, an attaching device movable longitudinally on said crossbar, means to move said attaching device and means to lock the same when adjusted, substantially as described.

2. A grain-heading machine having an adjustable header-frame, and a lever to tilt said header-frame, in combination with a cross-bar attached to said tilting-lever, said bar serving for the attachment of the neck-yokes or holdback-straps of the teams, an attaching device movable longitudinally on said crossbar, means to move said attaching device and means to secure the same on said cross-bar at any desired adjustment, substantially as described.

3. A grain-heading machine having an ad- 'j ustable header-frame, and a lever to tilt said header-frame, in combination with a cross-bar attached to said tilting-lever, said cross-bar serving for the attachment of the neck-yokes or holdback-straps of the teams, a longitudinally-adj ustable bar, an attaching device secured to said longitudinallyadjustable bar, a rearward-extending shaft carried by said tilting-lever and geared to said longitudinallyadjustable bar, and means to rotate said shaft, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

DELBERT F. MILLER.
